非晶合金具有许多优异的性能.然而,在室温下进行压缩或拉伸时,非晶合金通常沿着主剪切带方向发生脆性断裂,非晶合金较差的室温塑性严重制约了其在工程上的应用.已有理论和相关实验表明,非晶合金的机械性能与自由体积的含量密切相关.因此,充分认识非晶合金中自由体积的形成和演化规律进而发展调控自由体积的技术对非晶合金的开发应用具有重要的意义.
Amorphous alloys have many excellent properties.However, amorphous alloys usually undergo brittle fracture along the direction of the main shear band when they are compressed or stretched at room temperature, and the poor room temperature plasticity of amorphous alloys severely limits their performance in engineering Has been the theory and related experiments show that the mechanical properties of amorphous alloys is closely related to the content of free volume.Therefore, fully aware of the amorphous alloy in the formation and evolution of the free volume of the law to develop and control the volume of free technology Crystal alloy development and application of great significance.
